As technology becomes integrated into everyday life, the relationship between the human and machine must be kept in a balance. Not only does the technology have to perform its intended function, but it must do so in accordance with the dynamic parameters of the complex use environment, in a way that does not encumber the user either physically or mentally. The dissertation explores the challenges of such a scenario through an analysis of three core facets: Affordances, or the user interface cues that allow an intuitive means of operating a device; the aspect of simplicity and its effect on the use factors of the technology (while something might seem to be simple, it may actually be complex to use); and cognitive load in terms of user impact, as a result of utilizing the technology. These illustrate the challenges inherent in understanding the facets fundamental to human- machine interaction in a complex environment. The three factors will be explored first through an historical analysis of the work in each aspect. The theories at hand will be utilized to inform the creation of iterative generations of wearable sensory systems. By utilizing the systems in the field of dance, the theoretical aspects of the core factors can be gauged by actual implementation. Each implementation will be compared side by side to gauge differences in terms of movement dynamics and efficacy of execution. The study will reveal that the three core factors of affordance, simplicity and cognitive load combine synergistically to create a foundational methodology for seamless integration of technology in a complex use scenario. Furthermore, the facets of interoperability between devices in a complex use environment will be illustrated through the theory of intra-interactivity. Finally, the dissertation will illustrate the advantages of passive user interaction and its necessity in relation to the factor of cognitive load. / text
